Description
Technical field
The present invention relates to a kind of preparation methods of green composite buffering packaging material, belong to packaging material technology of preparing neck
Domain.
Background technology
With the development of science and technology the pressure of environment is also increasing.Short also increasingly apparent, the global energy of natural resources
More gradually protruded with climatic issues so that people will not only pay close attention to global economic development, more it is noted that the research and development of new energy and
Protection for natural environment.And amortizing packaging material to be used is led at this stage, and it is not to be difficult to degrade, it is harmful to environment,
The consumption of non-renewable resources is exactly exacerbated as raw material using the substance by oil extraction.And it uses now environmentally protective
The padded coaming of type can't substitute original buffering completely immediately due to cushion performance, use scope, price etc. reason
Material, therefore be necessary for the research of New Buffering packaging material.
Existing amortizing packaging material mainly includes foamed plastics, honeycomb cardboard and plant fiber cushion packaging material
Deng the foamed plastics for buffering is a kind of padded coaming with numerous honeycomb structures formed by foaming.Main product
Kind has PE（Crosslinked PE foam）、PS（Polystyrene foam）、EPS（Expanded polystyrene foam）And PU（Poly- ammonia is cruel
Foamed plastics）Have that density is small, easy processing shaping Deng, foamed plastics, cushion performance is good, and being applicable in for different humitures
The characteristics of scope is very wide, low thermal conductivity, thus with extensive in terms of transportation and packing are buffered.But due to source, cost, recycling and
The problems such as degradation, using being restricted, and is prepared by various methods slow using this natural resources of plant fiber
Rush packaging material.Oneself has through research at present：Agricultural crop straw and polylactic acid, poly- ammonia are cruel, waste paper and starch, crops stalk crushing
The a variety of materials such as object and bonding agent are raw material, through mixing, being crosslinked, foaming, toast the techniques such as sizing, natural drying, it is obtained respectively
Class amortizing packaging material.The forming process of abscess is divided into：The formation of nuclei of bubbles, expansion, 3 stages of stable curing.This material
Under low stress, have the advantages that degradable, raw material is cheap and easy to get, but it goes back in buffer capacity and its resilience etc.
There are limitations.
The content of the invention
The technical problems to be solved by the invention：It is not degradable for foamed plastics, environment is polluted, and plant fiber class is delayed
Although rushing packaging material, its is degradable, there are problems that limitation in terms of buffering with resilience, the present invention is first with new
Fresh Philippine's curtain clam meat is raw material, and after being crushed with lactic acid bacteria powder stirring, hybrid concurrency ferment is carried out with substances such as peptone, sucrose,
Filtrate is carried out with atlapulgite mixing decoloration, refilters concentration, obtain concentrate, then by itself and bamboo fibre, corn by filtering
The substances such as starch carry out mixing standing, are modified by the microorganism in concentrate, lower sediment are collected, finally by itself and wine
The substances such as stone acid, calcium carbonate are stirred heating, you can obtain green composite buffering packaging material.Green prepared by the present invention is answered
It is degradable to close amortizing packaging material, will not damage to environment, and with higher cushion performance and rebound degree.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
（1）Take fresh Philippine's curtain clam meat, its surface clean is clean, then with fresh Philippine's curtain clam meat quality 2.3~

Number meter, takes 46~49 portions of minced meat, 26~29 parts of peptones, 18~21 portions of sucrose, 9~12 parts of distilled water, 0.9~1.3 part of chlorination
Sodium stirs evenly, and obtains mixture；
（2）Said mixture is put into fermentation tank, addition is the 40~45% of fermenter volume, design temperature 22
~24 DEG C, with 100r/min stirrings fermentation 1~2 day, 33~35 DEG C are then raised temperature to, continues fermentation 2~3 days, in fermentation ends
Afterwards, the fermenting mixture in fermentation tank is filtered, filtrate is collected, by solid-liquid mass ratio 1:2, atlapulgite and filtrate are stirred
It mixes uniformly, stands 16~19min, then be filtered, collect filtered fluid and be concentrated in vacuo to the 50~55% of original volume, collect dense
Contracting liquid；
（3）It counts in parts by weight, takes 32~36 portions of above-mentioned concentrates, 18~22 parts of bamboo fibres, 10~12 parts of cornstarch
And 3~5 parts of sodium metasilicate, it stirs evenly, is placed in 24~34 DEG C, stand 10~15h, be subsequently placed in ultrasonator, set
Frequency is 48~52kHz, vibrates 30~40min, then stands 4~7h, removes supernatant liquor, collects lower sediment；
（4）Count in parts by weight, take 48~52 parts of above-mentioned lower sediments, 17~19 parts of polyglycolic acids, 4~6 parts of tartaric acid,
2~5 parts of calcium carbonate, 1~3 part of ethylenediamine and 0.7~1.3 part of odium stearate, are put into mixer and stir evenly, place into mold
In, design temperature is 205~210 DEG C, and pressure is 7~9MPa, and pressurize is molded 35~42s, 20~25s of heat preservation and dryness, then cold
But to room temperature, you can obtain green composite buffering packaging material.
The degradable substance contained in green composite buffering packaging material prepared by the present invention reaches more than 95%, water absorption rate
Less than 0.4%, dynamic buffering coefficient is more than 7.2, and static buffering coefficient is more than 4.1, and rebound degree is more than 85.25%, and it is complete
Degradable only needs 3~5 months.
Compared with other methods, advantageous effects are the present invention：
（1）Green composite buffering packaging material prepared by the present invention is degradable, and the degradable substance contained reaches 95%
More than, being completely degraded only needs 3~5 months, will not damage to environment；
